About

This study is designed to collect data which will be used to associate changes in EEG, neurocognitive performance, eNPC and clinical symptoms in concussion subtypes. The study will recruit males and females, 13-50 years old, from Concussion Centers/Programs, Sports Venues and Emergency Departments (ED) across the country, over an 18-month period (Phase 2, 12 months for Algorithm Development and Norming, and Phase 3, 6 months for Validation).

Full description

Phase 1 of this project (USAMRDC W81XWH-18-C-0157) was focused on building the automated/electronic NPC capability (eNPC). This protocol is for Phase 2, in which the CI multimodal brain function biomarker will be extended (Algorithm Development) with the inclusion of an automated ocular function measurement (AOFM), to expand the capability in the characterization of concussion. The study will also expand the range of applicability of the CI to ages 13-50 years old. Phase 2 will also include norming of eNPC across the age range. Phase 3 of the project will validate the algorithms developed in Phase 2, using the same protocol.

Enrollment: 1,318 patients

Sex: All

For head injured subjects

• Having sustained a traumatic closed head injury within 120 hours (5 days from time of injury at time of BrainScope assessment);
• GCS 13-15 at time of BrainScope assessment.

For non-concussed head-injured controls

• Having sustained a traumatic closed head injury but returned to play or deemed non-concussed following sideline (on-field) evaluation within the same game and enrolled in the study within 120 hours (5 days) from said incident.

• Current CNS active prescription medications taken daily, except for medication being taken for the treatment of Attention Deficit Disorders (ADD/ADHD); medication for smoking cessation; or medications for anxiety taken PRN (as needed);
• Forehead, scalp or skull abnormalities that prevents headset application for EEG data collection in injured/matched controls;
• History of brain tumor, brain surgery or known neurological disease including, Parkinson's, MS, Alzheimer's, dementia, epilepsy;
• History of TIA or Stroke within the last year;

• Prisoners.

For head injured subjects

• Loss of consciousness ≥ 20 minutes related to the concussion injury;
• Evidence of abnormality visible on Computerized Tomography (CT) of the head related to the traumatic event (note: neuroimaging is not required for enrollment);
• For current injury, hospital admission (other than the Observation Unit) ranging more than 24 hours due to either head injury or collateral injuries.

For non-concussed head-injured controls

• Loss of consciousness ≥ 20 minutes related to the head impact;
• Any focal neurological signs including aphasia, apraxia, diplopia, facial droop, dysarthria/slurred speech;
• Any score >3 on a 7-point Likert scale (0=none, 6=severe) for the following symptoms at the time of BrainScope assessment (compared to how the subject normally feels): headache, dizziness, balance problems, neck pain, feeling slowed down;

For matched controls and healthy volunteers

• Any focal neurological signs including aphasia, apraxia, diplopia, facial droop, dysarthria/slurred speech;
• Hospital admission (other than the Observation Unit) ranging more than 24 hours due to either head injury or collateral injuries in the past 6 months;
• Any score >3 on a 7-point Likert scale (0=none, 6=severe) for the following symptoms at the time of BrainScope assessment (compared to how the subject normally feels): headache, dizziness, balance problems, neck pain, feeling slowed down.

For healthy volunteers

• Legally blind in one or both eyes;
• History of eye surgery in the past year;
• Any known eye disorders including age-related macular degeneration (AMD), glaucoma, lazy eye, diplopia, cataracts, etc.

Trial design

1,318 participants in 3 patient groups

Injured and Matched Control Subjects

Description:

Head Injured subjects are defined as those who sustained a closed head injury and meet specified protocol inclusion/exclusion criteria. Matched Control subjects are enrolled based on matching criteria (for e.g. age, gender, and same population i.e. sports vs non-sports) to the head injured subjects. For all head injured and matched control group subjects, the full battery of tests will be performed. The injured pool will begin test procedures when a subject sustains a concussion injury. The matched control pool will follow the same time point/date interval as their matched injured subject. The matched control will be assigned by site to an injured subject and matched by age, gender, and sport (if applicable) or from the same population (if non-sport).

Treatment:

Diagnostic Test: Near Point Convergence

Diagnostic Test: SCAT5

Device: BrainScope Ahead 300iP-O

Healthy Volunteer Subjects

Description:

Healthy Volunteer subjects are defined as those who are normal subjects i.e. not head-injured meeting specified protocol inclusion/exclusion criteria.This group of subjects are recruited only for the purpose of collecting data for norming the electronic near point convergence measurement (eNPC). These subjects will only perform a limited battery of BrainScope tests at a single visit and will include data collection regarding their demographics, concussion history, signs and symptoms, sports information, etc. These subjects will not undergo EEG or neurocognitive assessment.

Treatment:

Diagnostic Test: Near Point Convergence

Diagnostic Test: SCAT5

Device: BrainScope Ahead 300iP-O

Non-Concussed Head Injured Subjects

Description:

A secondary group of non-concussed head-injured controls shall be also recruited who were observed to have a head impact/injury but were not restricted from play within the same game or deemed non-concussed following on-field/sideline evaluation by the standard of care at each site. They will perform the entire BrainScope battery of tests within 5 days after the incident and defined as Day 0 and a follow-up assessment at 15 Days following Day0

Treatment:

Diagnostic Test: Near Point Convergence

Diagnostic Test: SCAT5
